Contracts are like a double-edged sword — wielded correctly, they can quickly accumulate wealth; wielded incorrectly, they can wipe out your capital in an instant. My own trading style is quite aggressive: I split 300U into 10 parts, each time investing only 30U with 100x leverage. When the market moves in the right direction, just one point can double the capital; in the opposite direction, it’s an instant wipeout. It sounds crazy, but as long as you strictly follow discipline, you can survive in this knives-and-swords battlefield.

**Key Rule 1: Cut losses and run, don’t hope for a rebound**
I’ve suffered two big liquidation losses early on because I couldn’t bear to cut losses, always waiting for a market rebound to save the position. The result? Only when the account was wiped out did I realize — the market shows no mercy to any gambler. When reaching the stop-loss level, you must exit. Although accepting losses is tough, it’s better than holding on until liquidation, as at least you preserve the capital that can be used to rebound later.

**Key Rule 2: Stop trading immediately after five consecutive losses**
Market chaos is the easiest time to get chopped. I’ve set up a circuit breaker: after five wrong trades, I shut down immediately, no revenge trades. Rest for one night, then review the charts the next day. Usually, those troubles evaporate, and the previous entanglements are just ineffective moves.

**Key Rule 3: Take half of the profit every time you earn 3000U**
The numbers in my account are just paper wealth, which can evaporate at any time. My strict rule is: once the cumulative profit reaches 3000U, I withdraw 50% to a cold wallet. Only assets that are truly in hand count as real profit. Don’t get blinded by thoughts like “just one more doubling and it’ll be perfect,” which can lead to an empty basket in the end.

**Key Rule 4: Only trade in one-sided trends, never touch sideways markets**
In clear uptrends or downtrends, 100x leverage acts like a rocket booster; but in sideways consolidation, it turns into a harvesting machine for chives. When the direction is uncertain, I choose to lie flat and watch, never blindly place orders again. When the trend becomes clear, a decisive strike is far more efficient than frequent tinkering.

**Key Rule 5: Never risk more than 10% of your capital on a single position**
Don’t dream of hitting the jackpot with full margin overnight. To win, you first need to survive. I insist on trading only with 30U each time — enough to lose, steady to win. Small positions help maintain a stable mindset, allowing you to stay clear-headed and avoid being carried away by candlestick fluctuations.

Focusing on main cryptocurrencies like BTC, ETH, SOL, and BNB, I’ve summarized this methodology based on years of trading experience. The core is: learn to manage losses, master position discipline, and only then can you build a truly profitable system of your own.
